How to insert a link is clear:

$APPLICATION->AddHeadScript('jquery.js');
$APPLICATION->AddHeadScript('javascript.js');

And how to insert such a script, as highlighted in the picture:

Answer 1

If template.php is a component template, then create a script.js file in the same folder next to template.php, and drop the script into it. It will be automatically loaded when the component is connected. You can read about component templates here.
If by template.php you mean the site template: header.php or footer.php, then you can use

$APPLICATION->AddHeadString('
<script>
//some script
</script>
');

Answer 2

//template.php
<?if(!defined("B_PROLOG_INCLUDED") || B_PROLOG_INCLUDED!==true)die();
...
?>
<script>
//some script
</script>
